STUDY DESIGN: A genetic association study of 53 single nucleotide polymorphisms (SNPs) with adolescent idiopathic scoliosis (AIS). OBJECTIVE: To explore new predisposition genes of AIS in Chinese Han population SUMMARY OF BACKGROUND DATA.: A panel of 53 SNPs were reported to be associated with curve severity of AIS. However, there is still a lack of knowledge concerning the association of these SNPs with the susceptibility of AIS in the Chinese Han population. METHODS: A gene-based association study was conducted by genotyping the 53 SNPs of a prognostic test. DNA samples of 990 female patients with AIS and 1188 age-matched healthy controls were analyzed using the polymerase chain reaction-based Invader assay. The χ test was carried out to compare the differences of genotype and allele distributions between patients with AIS and healthy controls. RESULTS: A total of 4 SNPs were found to present significant differences in allele or genotype frequencies between the 2 groups. Compared with normal controls, patients were found to have significantly higher allele G of rs12618119 and allele A of rs9945359. Besides, patients were found to have significantly lower allele T of rs4661748 and allele C of rs4782809 than the normal controls. BIN1, CDH13, SETBP1, and SPATA21 genes could be associated with the susceptibility of AIS. CONCLUSION: Four new predisposition genes of AIS were identified on the basis of a large-scale case-control study. Putting all these findings together, it suggests that AIS is a multifactorial disease possibly involving different pathways such as development of central neural system and bone formation. Further studies exploring more predisposition gene are essential to illustrate the etiology of AIS and to guide the prevention or prognosis of the disease. LEVEL OF EVIDENCE: 3.
